PAPER BAG AND METHOD OF MAKlNG THE SAME.

SPECIFICATION forming part of Letters Patent No. 341,720, dated May11,1886.

Application filed February 3, H86.

To all whom it may concern:

Be it known that I, SAMUEL BAYLE, a citizen of the United States,residing in Philadelphia, Pennsylvania, haveinvented certainImprovements in Paper Bags and in the lllethods of Making the Same, ofwhich the following is a specification.

The main object of my invention is to simplify the folding ofbellowssided paper bags, so that they may, when desired for use, bereadily opened out into the satchelbottom form, and this objectl attainas fully described hereinafter.

In the accompanying drawings, Figure l is a perspective view of thebellowssided bag with closed bottom before it is folded. Fig. 2 is aview of the same in the reverse position. Figs. 3 and 4 are perspectiveviews of the bag in the dilferentstages of folding. Fig. 5i1lustratesthe finished bag; and Fig. 6 illustrates the same when opened outintothe satchel-bot tom form, ready for use.

Referring to Figs. 1 and 2, A A arethe flat sides, and B B the bellowssides, of the tube, all four sides being equal in width. The bottom ofthe tube is closed by a folded and pasted flap, a, or in any convenientmanner. I then open out the side folds, beginning at the open end of thebag, in the manner illustrated in Fig. 3, and as indicated by thearrows, so that the flat sides A A will become folded, as illustrated inFig. 4, into the bellows sides, while the sides 13 B will be opened out.This reversing of the flat sides and bellows sides, owing to theequality in width, causes the corners of the closed bottom to be pulledover in the act of opening the side folds, B B, thereby converting thesecorners of the closed bottom into cross-folds over the newly-formedSerial No. 190,717. (No model.)

flat faces of thebag, as shown in Fig. 4. The

bag is then finished by flattening out these folds to the formillustrated in Fig. 5, making a folded bag, which is ready for themarket, as a new article of manufacture. WVhen it is to be used, thefolds described will lend themselves to the ready opening of the baginto the square satchel bottom form illustrated in Fig. 6.

The sides A A and B B of the bag being allof the same width, asdescribed, the bag, when opened out, as shown in Fig. 6, will form aperfect square. This equality of the sides, and consequentreversibility, forms an important characteristic of the bag, for if thesides were unequal in width the opening out of the bellows sides and thefolding of the corners in the manner described could not beaccoinplished successfully.

I claim as my invention 1. The mode herein described of folding paperbags, said mode consisting in opening out the bellows sides, folding theflat sides of the tube into bellows form, and thereby folding thecorners of the closed bottom into crossl'olds over the new flat sides,substantially as specified.

2. As a new article of manufacture, the bellows-sided square paper baghaving the corners of the closed bottom lying in cross-folds over theflat faces of the folded bag, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

SAML. BAYLE.
